The National Institutes of Health (NIH) requires a brand-name Fujifilm Visualsonics high-resolution ultrasound imaging system for precise, real-time visualization of mouse embryos during in utero injections. The system is essential for developmental biology, gene delivery, and disease modeling research, and must include specific transducers, software, and accessories. Performance of services will be at the NIH campus in Bethesda, MD (9000 Rockville Pike, Building 10). Delivery is estimated at 90 days after receipt and acceptance of award. The government will award a firm fixed-price purchase order based on technical capability, price, and delivery.
